Skateboard Star Releases Insane Highlight Video

If William Spencer looks familiar, it's because he's played the lead role in a recent superhero movie. Sort of.

Spencer was a stunt double for The Amazing Spider-Man star Andrew Garfield. He worked closely with Garfield on the film, teaching Garfield how to ride a skateboard and even performing some stunts on camera.

Called the "Skate Ninja" for his dexterity on his board, Spencer has become famous from a series of YouTube clips that show him performing unbelievable skating stuns. See for yourself.
